Kusiyanitsa pakati pa matabwa ozungulira mbali imodzi ndi matabwa ozungulira awiri ndi chiwerengero cha zigawo zamkuwa.Sayansi yotchuka: matabwa ozungulira awiri ali ndi mkuwa kumbali zonse za bolodi, zomwe zingathe kulumikizidwa kudzera pa vias.Komabe, pali gawo limodzi lokha la mkuwa kumbali imodzi, yomwe ingagwiritsidwe ntchito pamabwalo osavuta, ndipo mabowo omwe amapangidwa angagwiritsidwe ntchito polumikiza mapulagi.

The luso amafuna awiri mbali matabwa dera ndi kuti mawaya kachulukidwe amakhala lalikulu, kabowo ndi ang'onoang'ono, ndi pobowo wa dzenje metallized amakhala ang'onoang'ono ndi ang'onoang'ono.Ubwino wa maenje opangidwa ndi zitsulo zomwe kulumikizana kwa wosanjikiza kumadalira kumagwirizana mwachindunji ndi kudalirika kwa bolodi losindikizidwa.

Ndi kuchepa kwa kukula kwa pore, zinyalala zomwe sizinakhudze kukula kwakukulu kwa pore, monga zinyalala za burashi ndi phulusa lamoto, likangosiyidwa mu dzenje laling'ono lidzachititsa kuti electroless mkuwa ndi electroplating kutaya mphamvu, ndipo padzakhala mabowo. opanda mkuwa ndi kukhala mabowo.Wakupha wakupha wa metallization.

Njira yowotcherera ya bolodi loyang'ana mbali ziwiri

Pofuna kuonetsetsa odalirika conduction zotsatira za mbali ziwiri mbali bolodi dera, tikulimbikitsidwa kuwotcherera mabowo kugwirizana pa bolodi mbali ziwiri ndi mawaya kapena zina zotero (ndiko kuti, kudzera-dzenje gawo la ndondomeko metallization), ndikudula gawo lotuluka la chingwe cholumikizira Kuvulaza dzanja la wogwiritsa ntchito, uku ndikokonzekera mawaya a bolodi.

Zofunikira pakuwotcherera mbali ziwiri za board board:
Pazida zomwe zimafuna kuumba, ziyenera kukonzedwa mogwirizana ndi zofunikira za zojambulazo;ndiko kuti, ziyenera kupangidwa poyamba ndi pulagi
Pambuyo pojambula, mbali yachitsanzo ya diode iyenera kuyang'ana mmwamba, ndipo pasakhale kusiyana kwa kutalika kwa zikhomo ziwirizo.
Mukayika zida zomwe zili ndi zofunikira za polarity, samalani kuti polarity yawo isatembenuzidwe.Pambuyo kulowetsa, mpukutu Integrated chipika zigawo zikuluzikulu, ziribe kanthu ndi ofukula kapena yopingasa chipangizo, sipayenera kukhala mapendekedwe zoonekeratu.
Mphamvu ya chitsulo chosungunula chomwe chimagwiritsidwa ntchito pochizira ndi pakati pa 25 ~ 40W.Kutentha kwa nsonga yachitsulo chosungunuka kuyenera kuyendetsedwa pafupifupi 242 ℃.Ngati kutentha kuli kwakukulu kwambiri, nsongayo ndi yosavuta "kufa", ndipo solder sichikhoza kusungunuka pamene kutentha kuli kochepa.Nthawi ya soldering iyenera kuyendetsedwa mkati mwa 3-4 masekondi.
Kuwotcherera ovomerezeka nthawi zambiri kumachitika molingana ndi mfundo yowotcherera ya chipangizocho kuchokera kufupi kupita kumtunda komanso kuchokera mkati.Nthawi yowotcherera iyenera kuphunzitsidwa bwino.Ngati nthawi yayitali kwambiri, chipangizocho chidzawotchedwa, ndipo mzere wa mkuwa pa bolodi lovala zamkuwa udzawotchedwanso.
Chifukwa chakuti ndizitsulo ziwiri, ndondomeko yowonongeka kapena yofanana ndi yoyika bolodi la dera iyeneranso kupangidwa, kuti musamangirire zigawozo pansi.
Pambuyo pogulitsa bolodi, fufuzani mozama kuti muwone komwe kulibe kuyika ndi kugulitsa.Pambuyo potsimikizira, chepetsani mapini osagwiritsidwa ntchito ndi zina zotere pa bolodi yozungulira, kenako ndikulowa munjira ina.
Mu ntchito yeniyeni, ndondomeko zoyenera ziyeneranso kutsatiridwa mosamalitsa kuti zitsimikizire mtundu wa kuwotcherera kwa mankhwala.

Ndi chitukuko chofulumira cha zamakono zamakono, zinthu zamagetsi zomwe zimagwirizana kwambiri ndi anthu zimasinthidwa nthawi zonse.Anthu amafunikiranso zinthu zamagetsi zogwira ntchito kwambiri, kukula kochepa ndi ntchito zambiri, zomwe zimayika zofunikira zatsopano pamagulu ozungulira.Ichi ndichifukwa chake gulu lachigawo la mbali ziwiri linabadwa.Chifukwa cha kuchuluka kwa matabwa ozungulira mbali ziwiri, kupanga matabwa osindikizira amakhalanso opepuka, ochepetsetsa, ofupikitsa komanso ang'onoang'ono.
